Monitoring VOCs in porewater in the unsaturated zone is now possible.
Sorbisense regularly offers new options for using the patented Sorbicell, which is used to monitor surface water, wastewater and groundwater.
The latest is almost as “ground-breaking” as the SorbiCell itself. Until now it has been difficult, if not impossible, to directly monitor for volatile substances in pore water in the unsaturated zone. But the environmental consultancy firm Ejlskov A/S in Aarhus combined the use of Sorbisense sampling equipment with the proven technology of soil water samplers. With this combination, a practical new method is made available, which allows for monitoring the presence of porewater-dissolved VOCs above the groundwater table. This provides a significantly improved basis to define and determine the leaching risk to the groundwater, and thus allows for better and more cost-efficient decisions to prevent the pollution in reaching the groundwater.
A simple construction with multiple options
The application uses SorbiCell VOC combined with suction cells, soil water samplers. When installed correctly, and applied with the correct procedures, the suctions cells extract capillary bound water from the soil matrix. The system demands no other resource than a container that is put under vacuum. The vacuum in the container then ensures a flow through of the Sorbicell over a period of time, fx. 2-3 weeks. The method is highly suitable for monitoring a site over longer periods of time.

The waste-sludge generated by primary and secondary (biological) treatment of municipal & industrial wastewater needs to be managed at every plant big or small. In the larger sewage treatment facilities waste sludge thickening and dewatering has always been assumed a necessity without the planners and designers thinking twice about the cost requirements. In the smaller and decentralized STP’s where available investment is always lower, the on-site waste-sludge management (thickening & dewatering) maybe compromised due to the high cost of investment, largely due to the comparative high cost of facilities (building, equipment, piping, auxiliaries, etc). The DEVISE “Containerized Sludge Dewatering Plant” (CSDP) provides a first class solution for the small STP’s at a reasonable cost and most importantly it comes in a fully automated package unit that is ready to “plug & play”.
